FOCUSSING
Mount a welding tool holder to the fixation arm with clamped electrode.
Turn the focus knob (10) to a medium enlargement setting.
Adjust the mounting height of the microscope head:
Hold the microscope head (8) with one hand without touching the lens and, with the other
hand, loosen the screw (9) of the head mount. The head can now be moved.
Look through the eyepieces and move the head up and down until the object seems to
be in focus.
Tighten the screw of the head mount again.
Adjust focus with the focus knob (10).
DIOPTRE SETTINGS
The rings for dioptre setting (2) are located on the eyepiece tubes (3). In the normal
position, the lower part of the sleeve is aligned with the marking on the eyepiece tube.
In case of eyesight deviations:
Only open the right eye, look through the right eyepiece (1) and set the focus using the
focus knob (10).
Then look through the left eyepiece with your left eye and adjust the focus by turning the
dioptre control (2) on the left tube (3) until the view is in focus.

CARE AND MAINTENENCE
The mezzo needs, under ordinary working conditions, only minimal care and
maintenance. Remembering a couple of points is crucial, though, to ensure proper
functioning and a long life for your welding device.
After the work is complete, cover device with the dust cover.
Regularly check the power plug, power cable and connector plug for damage.
Clean the device occasionally with a soft cloth or compressed air

6-1 MAINTENANCE OF THE OPTICAL COMPONENTS
Do not try to disassemble the optical components. Please turn to your local technical
support centre for repairs not described in this manual.
Remove dust particles with a special brush or with compressed air before cleaning the
lens surface. The respective accessories can be found in every photo shop.
Cleaning the eyepieces
Do not remove the eyepieces (1) from the eyepiece tubes (3).
Clean the outer surfaces and breathe on them while doing so.
Subsequently, dry the lens using an appropriate paper or cloth. Dry the lens with circular
movements, starting in the centre and working your way outwards. Avoid wiping a lens
that is already dry, as it might easily be scratched.
